Pertaining to the heart and blood vessels
Cardiovascular
system of blood vessels that carries blood between the heart and the lungs
pulmonary circuit
vessels that conduct blood between the heart and all body tissues except the lungs
systemic circuit
serous membrane that surrounds the heart
pericardium
large vessel on the posterior surface of the heart into which the cardiac veins drain
coronary sinus
visceral part of the pericardium on the surface of the heart
epicardium
muscle tissue of the heart
myocardium
inner lining of the heart chambers
endocardium
upper chambers of the heart
atria
ear-like structures; the parts of the heart that form the walls of the atria
auricles
cavities, such as brain ventricles filled with cerebrospinal fluid, or heart ventricles that contain blood
ventricles
opening between the atrium and the ventricle on each side of the heart
atrioventricular orifice
groove on the surface of the heart that marks the division between an atrium and a ventricle
atrioventricular sulcus
separates the left and right ventricles
interventricular sulci
heart valve between the right atrium and the right ventricle
tricuspid valve
muscles that extend inward from the ventricular walls of the heart and to which the chordae tendineae attach
papillary muscles
valve leading from the right ventricle to the pulmonary trunk
pulmonary valve
heart valve located between the left atrium and left ventricle
mitral valve
flap-like structures in the wall of the aorta near its origin that prevent blood from returning to the left ventricle of the heart
aortic valve
arteries that supply blood to the wall of the heart
coronary arteries
blood vessels that return blood from the venules of the myocardium to the coronary sinus
cardiac veins
